CAR-COUPLING.

PECIFIGATION forming part of Letters Patent No. 448,014, dated March 10,1891.

Application filed July 22, 1890. $erial No. 369,524. (No model.)

To all whom it Huey concern:

Be it known that I, JOSEPH M. FISK, a citizen of the United States, anda resident of Greenfield, in the county of Hancock and State of Indiana,have invented certain new and usefulImprovcmentsin Oar-Couplings; and Ido hereby declare that the following is a full, clear, and exactdescription of the invention, which will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, which form a part of this specification.

My invention relates to improvements in car-couplings which areautomaticallycoupled by the coming together of the cars, thus obviatingthe necessity of a brakeman or other person going between the cars forsuch purpose, and thus lessening the liability of injury to suchpersons.

The object of the invention is to provide a device of the abovecharacter which shall be simple and economical in construction, durablein use, and efficient and reliable in operation.

The invention consists in the novel construction and combination ofparts hereinafter fully described, and specifically pointed out in theclaim.

In the accompanying drawings, Figure l is a plan view of a car-couplingconstructed according to my invention. Fig. 2 is a perspective view ofone of the coupling-heads and draw-bars detached.

In the said drawings, the reference-n ume'ral l designates draw-heads,which may be of any ordinary or 'suitable construction. These draw-headsare secured to the ends of the cars, and passing through centralapertures therein are the round cylindrical draw-bars 2, having nuts orheads 3 at their inner ends, by which they are held in place. At theirouter ends these draw-bars are provided with coupling-heads 3',consisting of rectangular blocks having outwardly-projecting hooks 4 attwo diagonal corners, the hooks of each drawhead being placed oppositelyto each other,

so as to interlock when brought together.

that is to say, the upper and lower hooks of one draw-bar are placed onthe right and left sides of the coupling-head, respective] y, while thecorresponding hooks of the other coupling-head are placed on the leftand right sides, respectively, of the same, as will readily beunderstood by reference to the drawings. The ends of these hooks arebeveled or curved for a purpose hereinafter explained. The outer facesof the couplingheads are curved from the inner sides of thehooks totheir opposite sides, so as to correspond with thecurved ends of thehooks. Intermediate of the end walls 5 of each draw-head is a coiledspring 6, one end of which is secured to the drawbar and the other endto one of the said end walls, the tendency of the springs being to keepthe hooks of the coupling-heads in a horizontal plane.

The numeral 7 designates arms or rods secured to each coupling-head, forthe purpose of rotating or turning the same to disengage the hooks foruncoupling.

The operation is as follows: Upon the cars coming together, the beveledor curved ends of the hooks will strike each other, which will slightlyrotate the coupling-heads, allowing the hooks to pass each other, whenthey will assume their normal position by means of the coiled springsand become engaged, thus coupling the cars, as seen in Fig. 2. When itis desired to unoouple the cars, one of the coupling-heads is turned bymeans of the arm or rod 7 secured thereto, which will cause the hooks tobe disengaged, as seen in Fig. 3.

Having thus described my inventiomwhat I claim is- In a car-coupling,the combination, with a draw-head, of an oscillatory cylindrical bar
